Haven't seen any mention of Factorio in this thread. It's not as much of a puzzle game (except when going for extreme optimisation) but a resource management game.
Factorio has a lot in common with writing a fun new language that you don’t know how to abstract things in, figuring out as you go. Spaghetti bases will bite you just the same way as spaghetti code. And once you get the hang of it, it’s all about scaling, becoming crazier and crazier, until you have entire bases built with a swarm of flying robots in a single click. Can’t recommend it enough – but unlike Opus Magnum, Factorio is, as mentioned, definitely not a casual game.
